Revisiting the dynamics of the Prometheus-Pandora system
Demétrio Tadeu Ceccatto, Nelson Callegari, Gabriel Teixeira Guimarães
This study revisits the dynamics of Prometheus and Pandora. The analysis focuses on their current orbits and considers mutual perturbations and the non-spherical shape of Saturn. N…
Orbital Dynamics of Atlas (S XV): Its Current Orbit and the Recent Past
Demétrio Tadeu Ceccatto, Nelson Callegari, Gabriel Teixeira Guimarães +1
This study comprehensively analyzes Atlas's current orbit, focusing on the secular and resonant perturbations caused by Prometheus, Pandora, and Saturn's oblateness. We performed n…
A Hamiltonian for 1/1 Rotational Secondary Resonances, and Application to Small Satellites of Saturn and Jupiter
Nelson Callegari
In this work, we study the dynamics of rotation of the small satellites Methone and Aegaeon and revisit previous works on the rotation of Prometheus, Metis, and Amalthea. In all ca…
Dynamical characterization of the 6/1 mean motion resonance between Quaoar's ring and Weywot
Adrián Rodríguez, Bruno Morgado, Nelson Callegari
Recently, it has been reported the discovery of a dense ring around the trans-Neptunian object 50000 Quaoar. The ring particles seem to be very close to the 6/1 mean motion resonan…
The orbit of Aegaeon and the 7:6 Mimas-Aegaeon resonance
Nelson Callegari, Adrián Rodríguez
Aegaeon (S/2008 S 1) is the last satellite discovered by the Cassini spacecraft at the end of the 2000s. Like the satellites Methone and Anthe, it is involved in mean motion resona…
The current orbit of Atlas (SXV)
Demetrio Tadeu Ceccatto, Nelson Callegari, Adrián Rodríguez
With the success of the Cassini-Huygens mission, the dynamic complexity surrounding natural satellites of Saturn began to be elucidated. New ephemeris could be calculated with a hi…
